Is there any version specific pokemon?
Pokemon Let's go being a remake of Red and Blue, I wonder... is there, just like there was in Red and Blue, some pokemon that can only be caught in Pikachu or Eevee?
If yes, what are they?
Solution 1:
Yes, Let's Go Pikachu and Let's Go Eevee each have exclusive Pokémon that will allow you to catch1 in each version. According to this guide, the exclusives are:
Let's Go Pikachu
Oddish, Gloom, Vileplume, Sandshrew, Sandslash, Growlithe, Arcanine, Grimer, Muk, Scyther, Mankey, Primeape
Let's Go Eevee
Bellsprout, Weepinbell, Victreebell, Vulpix, Ninetales, Meowth, Persian, Koffing, Weezing, Ekans, Arbok, Pinsir
1. In Let's Go Pikachu, I was able to trade 5 Growliths for a Persian in Vermilion City. In Let's Go Eevee, a friend of mine was able to trade 5 Meowths for an Arcanine. I don't know all of these instances, but I do know of this exception.
